Longtime Tesla battery supplier Panasonic is working on new innovations that could increase its cells’ density by 20% by 2030. If achieved, the improvements could boost the driving range of electric vehicles even if the cars use the same battery packs they are equipped with today. 

In the case of the Tesla Model Y, the improved energy density could result in the vehicle getting an extra 62 miles of range without changing its battery size. More energy-dense batteries could also allow manufacturers to design and produce electric cars that are lighter and more spacious while still offering long range. 

Panasonic’s battery density targets were related to Reuters by the company’s chief technology officer, Shoichiro Watanabe, during an interview. According to Watanabe, Panasonic is looking to achieve its battery density gains through the use of new additives that would allow individual cells to run at a higher voltage without damaging performance. 

“The race among battery makers has been to come up with more potent and effective additives,” the Panasonic CTO said.

 A 20% increase in energy density could translate to an energy density of 900 watt-hours per liter, a substantial improvement over Panasonic’s most advanced cells today, which feature 750 watt-hours per liter. Watanabe mentioned that Panasonic is planning on achieving its battery density gains over several years, though he did not mention when the improved cells would begin their rollout. 

Panasonic is extremely busy with its battery supply deal with Tesla, with the Japanese company expected to start the mass-production of the American electric car maker’s 4680 batteries during the financial year starting April 2023. Panasonic is also reportedly reviewing sites for new battery production activities in the United States. 

So far, a Panasonic spokesperson has declined to provide a comment on whether the company’s new battery technologies would be incorporated in Tesla’s 2170 or 4680 cells. Tesla, for its part, has also remained silent about the matter.

Saudi artificial intelligence firm HUMAIN has confirmed a $3 billion Series E investment in xAI just weeks before the startup’s merger with SpaceX.

The transaction converts HUMAIN’s xAI stake into SpaceX shares, positioning the Saudi-backed firm as a significant minority shareholder in the newly combined entity.

The investment gives HUMAIN exposure to what has been described as one of the largest technology mergers on record, combining xAI’s artificial intelligence capabilities with SpaceX’s scale, infrastructure, and engineering base, as noted in a press release.

“This investment reflects HUMAIN’s conviction in transformational AI and our ability to deploy meaningful capital behind exceptional opportunities where long-term vision, technical excellence, and execution converge, xAI’s trajectory, further strengthened by its acquisition by SpaceX, one of the largest technology mergers on record, represents the kind of high-impact platform we seek to support with significant capital” HUMAIN CEO Tareq Amin stated.

The investment also positions HUMAIN for potential long-term equity upside should SpaceX proceed with a public offering.

The investment expands on an existing partnership announced in November 2025 at the U.S.-Saudi Investment Forum. Under that agreement, HUMAIN and xAI committed to jointly develop more than 500 megawatts of next-generation AI data center and compute infrastructure in Saudi Arabia.

The collaboration also includes deployment of xAI’s Grok models within the kingdom, aligning with Saudi Arabia’s broader strategy to build domestic AI capacity and attract global technology players.

HUMAIN, backed by the Public Investment Fund, is positioning itself as a full-stack AI player spanning advanced data centers, cloud infrastructure, AI models, and applied solutions. The Series E investment deepens its role from development partner to major shareholder in the Musk-led AI and space platform.

Tesla’s Giga Berlin plant manager is now under investigation after a complaint from trade union IG Metall, escalating tensions ahead of next month’s works council elections. 

Prosecutors in Frankfurt (Oder) confirmed they have opened a defamation probe into Gigafactory Berlin plant manager André Thierig, as per a report from rbb24.

A spokesperson for the Frankfurt (Oder) public prosecutor’s office confirmed to the German Press Agency that an investigation for defamation has been initiated following a criminal complaint filed by IG Metall against Thierig.

The dispute stems from Tesla’s allegation that an IG Metall representative secretly recorded a works council meeting using a laptop. In a post on X, Thierig described the incident as “truly beyond words,” stating that police were called and a criminal complaint was filed.

“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons, he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote in a post on X.

Police later confirmed that officers did seize a computer belonging to an IG Metall member at Giga Berlin. Prosecutors are separately investigating the union representative on suspicion of breach of confidentiality and violation of Germany’s Works Constitution Act.

IG Metall has denied Tesla’s allegations. The union claimed that its member offered to unlock the laptop for review in order to accelerate the investigation and counter what it called false accusations. The union has also sought a labor court injunction to “prohibit Thierig from further disseminating false claims.”

The clash comes as Tesla employees prepare to vote in works council elections scheduled for March 2–4, 2026. Approximately 11,000 Giga Berlin workers are eligible to participate in the elections.

Tesla wins FCC approval for wireless Cybercab charging system

The decision grants Tesla a waiver that allows the Cybercab’s wireless charging system to be installed on fixed outdoor equipment.

Tesla has received approval from the Federal Communications Commission (FCC) to use Ultra-Wideband (UWB) radio technology in its wireless EV charging system. 

The decision grants Tesla a waiver that allows the Cybercab’s wireless charging system to be installed on fixed outdoor equipment. This effectively clears a regulatory hurdle for the company’s planned wireless charging pad for the autonomous two-seater.

Tesla’s wireless charging system is described as follows in the document: “The Tesla positioning system is an impulse UWB radio system that enables peer-to-peer communications between a UWB transceiver installed on an electric vehicle (EV) and a second UWB transceiver installed on a ground-level pad, which could be located outdoors, to achieve optimal positioning for the EV to charge wirelessly.”

The company explained that Bluetooth is first used to locate the charging pad. “Prior to the UWB operation, the vehicular system uses Bluetooth technology for the vehicle to discover the location of the ground pad and engage in data exchange activities (which is not subject to the waiver).”

Once the vehicle approaches the pad, the UWB system briefly activates. “When the vehicle approaches the ground pad, the UWB transceivers will operate to track the position of the vehicle to determine when the optimal position has been achieved over the pad before enabling wireless power charging.”

Tesla also emphasized that “the UWB signals occur only briefly when the vehicle approaches the ground pad; and mostly at ground level between the vehicle and the pad,” and that the signals are “significantly attenuated by the body of the vehicle positioned over the pad.”

As noted by Tesla watcher Sawyer Merritt, the FCC ultimately granted Tesla’s proposal since the Cybercab’s wireless charging system’s signal is very low power, it only turns on briefly while parking, it works only at very short range, and it won’t interfere with other systems.

While the approval clears the way for Tesla’s wireless charging plans, the Cybercab does not appear to depend solely on the new system.

Cybercab prototypes have frequently been spotted charging at standard Tesla Superchargers across the United States. This suggests the vehicle can easily operate within Tesla’s existing charging network even as the wireless system is developed and deployed. With this in mind, it would not be surprising if the first batches of the Cybercab that are deployed and delivered to consumers end up being charged by regular Superchargers.
